More than 4 million people across five states were under winter storm alerts on Sunday as heavy lake-effect snow continued to bury the Great Lakes region, prompting emergency declarations and the deployment of National Guard troops to rescue stranded motorists.
Another day of intense lake-effect snow bands was occurring Sunday, especially in western New York, which has already received more than 40 inches of snow since Thursday and is expecting up to 24 more inches on Sunday into Monday.
Parts of New York, Pennsylvania, Ohio, Michigan and Wisconsin were under winter alerts as of Sunday.
